653254 ÷ 91 
The aim is to understand the frequency of 91 in 653254.

Going ahead to step 1:
The number 91 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 91

Step 2:
65 divided by 91 is 0 with a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Take the next digit (3) from the dividend and append it to 65, then repeat: 653 / 91

Moving on to step 3:
653 divided by 91 is 7 with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 637 from 653 leaves us with 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 91

Advancing to step 4:
If we divide 162 by 91, we get 1 and a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 71.0
The remainder is 71 after subtracting 91 from 162.
Include the next digit (5) from the dividend after 71, then repeat: 715 / 91

Moving on to step 5:
91 goes into 715 7 times with a remainder of 78.
The next digit of our result is 7. 
Result so far: 717.0
If we subtract 637 from 715, we get 78.
Append the next digit (4) from the dividend to 78 and continue with: 784 / 91

Step 6:
91 goes into 784 8 times with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 7178.0
If we take 728 away from 784, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 7:
91 can be fit into 560 6 times, resulting in a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 7178.6
If we take 546 away from 560, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
When dividing 140 by 91, we get 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 7178.61
If we subtract 91 from 140, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 9:
When dividing 490 by 91, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 7178.615
Deduct 455 from 490 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
91 can be fit into 350 3 times, resulting in a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 7178.6153
Deduct 273 from 350 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 11:
If we divide 770 by 91, we get 8 and a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 7178.61538
If we subtract 728 from 770, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
When dividing 420 by 91, we get 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 7178.615384
If we subtract 364 from 420, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
If we divide 560 by 91, we get 6 and a remainder of 14.
The next digit of our result is 6. 
Result so far: 7178.6153846
If we take 546 away from 560, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 14:
If we divide 140 by 91, we get 1 and a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 7178.61538461
Subtracting 91 from 140 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Our division results in 7178.61538461 with a remaining 4.9e-08.
